Trailhead is located 4.5 miles down Mill Brook Road, off of Route 110 in Stark, New Hampshire. Park beyond the bridge on the right side of the road and walk to the trail just East of the bridge crossing Mill Brook.
This trail crosses to the Kilkenny Ridge Trail and is a shorter, but steeper route to scenic Unknown Pond than from the Southern Trailhead. There are designated tent sites and an outhouse at Unknown Pond, but not at the trailhead. Mill Brook Road is gated closed in the winter.
